Reorder the terms:
13gklo + 13gklo + 52glo = log(13) * 21

Combine like terms: 13gklo + 13gklo = 26gklo
26gklo + 52glo = log(13) * 21

Reorder the terms for easier multiplication:
26gklo + 52glo = 13 * 21glo

Multiply 13 * 21
26gklo + 52glo = 273glo

Solving
26gklo + 52glo = 273glo

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '-273glo' to each side of the equation.
26gklo + 52glo + -273glo = 273glo + -273glo

Combine like terms: 52glo + -273glo = -221glo
26gklo + -221glo = 273glo + -273glo

Combine like terms: 273glo + -273glo = 0
26gklo + -221glo = 0

Factor out the Greatest Common Factor (GCF), '13glo'.
13glo(2k + -17) = 0

Ignore the factor 13.

Subproblem 1

Set the factor 'glo' equal to zero and attempt to solve: Simplifying glo = 0 Solving glo = 0 Move all terms containing g to the left, all other terms to the right. Simplifying glo = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(2k + -17)' equal to zero and attempt to solve: Simplifying 2k + -17 = 0 Reorder the terms: -17 + 2k = 0 Solving -17 + 2k = 0 Move all terms containing g to the left, all other terms to the right. Add '17' to each side of the equation. -17 + 17 + 2k = 0 + 17 Combine like terms: -17 + 17 = 0 0 + 2k = 0 + 17 2k = 0 + 17 Combine like terms: 0 + 17 = 17 2k = 17 Add '-2k' to each side of the equation. 2k + -2k = 17 + -2k Combine like terms: 2k + -2k = 0 0 = 17 + -2k Simplifying 0 = 17 + -2k The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
